In this example we connect a DHT11 sensor our Arduino, again we will display the temperature and this time the humidity as well on our LCD4884 shield. In this example we connected the data pin of the DHT11 to Pin 9. VCC and GND were derived from the shield.

Here’s a picture of the shield used

and here is the DHT11 breakout board, this simplifies things as it contains the necessary resistor already fitted otherwise you need to fit a 4k7 between Vcc and the data pin. You can also plug this into either a breadboard or simple connect dupont cables from the shield to the breakout
